T all whom it may concern:

Be it known that I, WILLIAM R. KNio-H'r, a subject of the Kingof Great Britain, and a resident of Belleville, county of Essex, and State of New Jersey, have invented'new and useful Improvements in' Playing-Balls, of which the following'is aspecification.

The object of the invention is to construct a playing-ball with means which will aid-its flight and which will place the ball under controlin all departments of the game in which it is employed. r The invention preferably relates to that class of playing-balls which are especially adaptedfor the purpose of golf and which have a liquid center.

In performing my invention a playing ball having such a center is provided with one or more balls which are free to move about in the liquid contained in the playingball and which balls havea specific gravity greater than said. liquid.

As showing a specific embodiment of the invention reference is made to the drawing forming a part of this specification and in which drawing.-

Figure 1 discloses a playing-ballpartially" broken away so as to show-its construction.- Figs 2, 3 and 4 show cores of difi'erent construction which may be used in the manu-, facture of playing-balls that embody my invention.

. The playing-ball comprisesa bag, container or receptacle A that is filled with a 5 liquidB. 'Around this bagon container A there is preferably wound, under a high de- .gree of tension; a rubber tape that may be for example approximately one inch in l width. This rubber tape is. comparatively thin but when wound under a high degree of tension imparts great pressureupon the liquid in the bag or con tainer-A. The wind-. ings of ta e are indicated by the reference character and around them there is wound under a high degree of tension-what may be coxisidered a thread of rubber, which thread before winding may be 'approximately of an inch inwidth, these windings of r'ub ber thread being indicated by the reference character D. Finally there is placed upon and around these windin any suitable wear-resisting casing E, or example of gutta'percha. The bag or container A that is shown in Fig. 1 is of the same construction'as that shown in Fig. 3 1n thatthe bag or container comprises a fabric portion a surrounded by a rubber portion 1). This fabric is provided in order to protect the rubber portion from the blows that are imparted to the bag by the ball F. This ball has a specificgravit heavier than the liquid and may be made or example of weighted rubber or metal or composition. The parts which are shown in Figs. 2, 3 and fl may be considered the coresof the playing-balls of which they substantially constitute a part and from an inspection of the drawing it willbe seen thatthey are made by placing in the bag or'container the ball F and liquid B and then tying thethroat or neck of the bag by a rubber thread 0. In the form of'core shown in Fig. 2 there .is not provided any fabric a in combination with the rubber portion 1) and while such a bag or container will serve alimited period of time still it will not-be as success ful as a bag which is reinforced or protected by a layer of fabric orthe. equivalent thereof.

0 The. bag which is used in the core shown m Fig. 4 comprises the fabric a that lS" C0Y,-

ered on the exterior and interior by layers of rubber band 6. The inner layer 6 of rubber of c urse serves to protect the fabric 'a and the fa ric a which serves as a;reinforcing material-An turn serves to protect the outer layer -'of rubber 6, thus making a bag having certain advantageous features. A considerable advantage is derived from placing the ball F that is heavier than the liquid in'theliquid that is contained within the core. In the first place-the flight of the i playing-hall is increased; moreover, when the playing-ball is'given what is known by. players as a back-spin it will fall dead; this evideiitlyresu'lting from the ball F having a certain inertia and tending to remainistill while the remainder of the playing-ball inw .cluding the liquid tends to rotate and thus the ball F acts as a damper upon the liquid 10o to brakeor retard the movement of the liquidand, consequently that ofthe rest of the playing-ball structure.

As previously stated the ball F is of a ma-' terial that is of a specific gravity greater than the liquid B and the ball F if made-of a hard composition or a metal such as hardened steel should-be given a smooth surface in or'der that the ball may not puncture the bag or container A. While there isshown no.

only one ballwithin. the liquid still a plu-.f rality of balls may be employed if desired.-

' The improvements herein set forth are not limited to the precise construction and arrangement shown and described, as they may be embodied in various forms and modifications Without departing from the spirit and scope ofthe invention.

What I claim is: I

1. A playing-ball comprising in combination a rubber bag 'or container filled with liquid and containing therein a metal ball, windings in the form of a rubber-tape surrounding said bag, windings in the form of a rubber thread surrounding the windings of tape, and a wear-resisting casing on the exterior of said windings. v

2. A playing-ball comprising in combination a container having therein a liquid and a ball free to move in .said liquid, windings fabric for protecting the rubber and having in the container a liquid and a ball of specific gravity greater than the liquid, which ball is free to move in said liquid; windings of rubber surrounding. said container, and a wear resisting casing surrounding said windings.

5. A playing-ball having in combination bag comprising a layer of rubber and a layer ,:this 17th day of September, A. D. 1915. or members in said liquid which member or members have a specific gravity greate'r'thari the liquid, rubber windings about said bag, and a wear-resisting casing constituting the of fabric, liquid filling said bag, a member outer portion of the playing-ball.

G. A playing-ball having a core-which comprises'a bag having: a layer of fabric or other reinforcing material and a layer of rubber, an incompressibleliquid in said bag,

and a smooth hardball'insaid bag', windings about said bag, and a wear-resisting casing constituting the outer portion of. the playing-ball. 1 r I 7 A core for playing-balls .comprising in combination a casing having a layer of fabric or other reinforcing material, liquid filling said casing, and a ball free to move in said liquid.

8. A playing-ball comprising in combination a liquid-tight bag having a layer of fabric or other reinforcing material, liquid filling said bag, and. a ball free to move in said liquid, the fabric or other reinforcing material being provided tov protect thebag from injury by said ball; windings of rubber surrounding said ball, and a wear-resisting casing surrounding said rubber windings.

9. A playing-ball-comprising in combina- -tion-a receptacle containing liquid, a ball free to move in said liquid, rubber windings surrounding said receptacle, and a wearresisting casing upon and surrounding said rubber windings, said ball being'of a' higher specific gravity than the liquid inwhich. it is contained. I

10. A playing-ball comprising in combina tion a receptacle, a liquid contained therein, a ball free to move-in said liquid, windings of rubber mounted'upon. and surrounding said receptacle, and a wear-resisting casing upon and surrounding said rubber windings, the casing containing the liquid comprising as a part thereof a layer of fabric or other reinforcing material.
